Applied Adhesion Science

Table 2 Shear bond strength means and standard deviation (±SD) for enamel and porcelain

Substrate	SBMP	SB	CLSE	SBU		Positive control	Negative control
Substrate	SBMP	SB	CLSE	SE	ER	Positive control	Negative control
Enamel	19.0^b (±10.2)	26.6^a (±9.3)	26.0^a (±8.5)	23.5^ab (±8.4)	22.6^ab (±9.9)
Porcelain					29.0^a (±6.9)	21.0^b (±7.0)	5.3^c (±2.7)

SBMP: Scotchbond Multipurpose; SB: Single Bond 2; CLSE: Clearfil SE Bond; SBU: Scotchbond Universal; SE: self-etch technique; ER: etch-and-rinse technique; Positive control: Silane plus SB; Negative control: no material.
Distinct letters in the same row indicate statistically significant differences (p < 0.05).
